GLASS-FURNACE.

SPECIFICATION forming part of Letters Patent No. 452,462, dated May 19, 1891. Application filed July 3, 1890. Serial No. 357,6 71. (No model.)

To @ZZ whom, it may concern: for working, and as heretofore constructed Be it known that I, JULES AUGUST IVEYER, necessitate an almost or entire tearing down a citizen of the United States, and a resident of the furnace to make repairs. It is to obof Celina, in the county of Mercer and State Viate this great fault that has been my prime 55 5 of Ohio, have invented certain new and useful object in this present invention, as well as Improvements in Glass-Furnaces; and I do the improvement generally in the art, this declare the following to beafull, clear, and eX- invention being so constructed that repairs act description of the invention, such as will may be made on any portion thereof without enable others skilled in the art to which it apdisturbing contiguous construction, and the 6o ro pertains to make and use the same, reference parts made more durable, and the glass probeing had to the accompanying drawings, and duced of better comparative quality, and the to the letters of reference marked thereon, action of each pot continues, the details of which form a part of this specification. all of which are hereinafter fully'speciiied.

Thisinvention relates to furnaces, and more The walls and floor of the furnace are travo 5 15 especially to that class of furnaces in which ersed by tlues for the purpose kof keeping the the material necessary is mixed and melted same cool bya circulation of air therein. The into glass and delivered to a place from which combustion-chamber A is formed by a fioor it can be conveniently gathered, the invenand crown d and a', respectively, and sides a2, tion consistingr in several novel details and and has ends a3 and aft, front and back, re- 7o zo additions to the construction heretofore emspectively. Through the wall as is a iiue or ployed, as will be hereinafter fully specified. openingb,which communicates with the batch In the accompanying drawings, Figure 1 is heating and mixing chamber B, into which is a longitudinal vertical section of the device thrown the mixed batch by way of the door through the center thereof, showing the batchb', stirring-holes h2 being provided and coin- 75 2 5 preparing chamber, the'melting crucibles and munication being had with the smoke-stack their interior connections, the boot, and the by means of the iiue h3, extending into said flues and gas-inlet. Fig4 2 is avertical crossstack C from the chamber B. The inclinasection on the line 2 2, Fig. l, showing lthe* tion of the flue b causes the batch to flow gas-jets and air-eduction flues, air-heating freely into the pot G in case it should become 8o 3o flue, the eduction-lue for the refuse pro- Huid or partially so. By means of this conducts of consumption, and the reducing-pot. struction the batch can be heated and the Fig. 3 is a vertical cross-section on line 3 3, gases evolved before it is passed into the melt- Fig. l, showing the rening-pot, the educing and refining pots, and this will be done tion-flue, and the short iiues connecting the in a position in which the batch may be S5 35 combustion chamber therewith, dampers stirred and all the gases of whatever nature therein, and the flue wherein air is heated for eliminated from the mass.

F-igs. of the iiues f, which connect with the heat- 6, 7, and 8 are perspective views, respecting-flue F, extending between the crown a ively, of the reducing, melting, and refining and the wall f', so that heat is conveyed from 9 5 45 pots. Fig. 9 is a transverse vertical section the chamber A and fine D into the air circuon the line t 4: of Fig. l. lating through said flue after entering at its In the figures like reference-marksindicate open end, as shown in Fig. l, being drawn in corresponding parts in all the views. by the current of gas issuing from the pipes Furnaces for this purpose require frequent E in the flues f, asbest shown in Figs. l and roo 5o repairing owing to Jthe intense heat required 2, the pipes E having on their ends jets or to melt the glass to the desired consistency burners of the desired size and form to govern the direction the gas takes on its introduction into the comlnistion-chamber A and valves to govern its quantity. As many ot these pipes and their corresponding air-llues f may be employed as desired; but the prin cipal heat should be applied to the reducingpot G of the series of pots G, ll', and I, constructed and arranged after the manner which will now be described. The reducing-pot G receives the batch after it is heated in the chamber B by way of the ilue l), and should be sufficiently deep to hold the batch in its granular form, although it generally comes from the chamber I3 partially melted inform, and is thoroughly reduced in the pot G to a stiff consistency, the material melted, and hence in best condition, settling to the bottom and passing into the next pot II through the duets .I between said pots Gand ll,in which pot I'I it. is further heated, the clearest and hottest glass settling and passing through the ducts .T into the pot I, where it is further relined and gathered from the lower portion through the boot K, which is curved and extends Vfrom near the bottom of the pot I through the front a3. There may be several of these boots in the one pot I, all being exactly alike and operating to allow the gathering of the glass withoutallowing the inux of cold air or the eilux of heat, the., into or from the combustion-chamber A. The pots G, II, and I are formed substantially as shown in Figs. 6, 7, and 8, respectively, and are made of material of sufiiciently refractory qualit-y, the pots G and I having offsets g on the side next the pot 1I, and said pot Il has said offsets g on the sides, by reason of which a reetangularspaee is left at the tops between each pot when assembled, into which is fitted a refractory tile Il, which is perforated longitudinally and has connection exteriorly of the furnace for the admission of air, and extends somewhat above the tops of the pots,- so as to form a firebridge and protect the tops of the pots at that point, where they would otherwise receive great heat. To remove a pot it is only neces- 45e/lee sary to remove this tile li and take the pot out, setting` a new one in its place. In each of the opcningsj of the potsis placed alining or bushing .l of refractory material, forming a duet [or the passage ol glass from one pot to the next.

lilues and /ntraversc the bottom of the furnace, the l'ormcr passing transversely through and having exterior openings at both ends. The latter pass from exterior openings in the front to tlues 7e', extending upward through the back to the chimney.

Having thus described my invention, what I claim as new, and desire to secure by Let` ters latent, is*- l. In a furnace, the combination of the chamber i5, the combustion-chamber A, the melting-pots placed in the said combustionchamber, the inclined passage l), leading from the chamber B to the pots, the tiles Inseated in recesses formed between the pots and having ilues passing longitudinally through them and connected with Ilues leading through the walls to the exterior of the furnace, and the ducts J, placed in coincident apertures passing through the bottoms of the adjacent sides of the pots, substantially as and for the purpose specified.

2. In a furnace, the combination of the combustionchamber, the communicating pots placed in said chamber, the flue F, formed over the combustion-chamber and having an exterior opening, the iiue D, formed over the flue F and leading to the chimney, the llucsf, leading from the flue F to the combustioncharnber, the gas-jets E, entering the lower ends of the tiues f, and the llues d, leading from the combustion-chamber to the flue D, substantially as and for the purpose specified.

In testimony whereof I hereunto aiiix my signature in presence of two witnesses.

JULES AUGUST WEYER.
